Essay topics:

As early as the twelfth century A.D., the settlements of Chaco Canyon in New Mexico in the American Southwest were notable for their "great houses," massive stone buildings that contain hundreds of rooms and often stand three or four stories high. Archaeologists have been trying to determine how the buildings were used. While there is still no universally agreed upon explanation, there are three competing theories.
One theory holds that the Chaco structures were purely residential, with each housing hundreds of people. Supporters of this theory have interpreted Chaco great houses as earlier versions of the architecture seen in more recent Southwest societies. In particular, the Chaco houses appear strikingly similar to the large, well-known "apartment buildings" at Taos, New Mexico, in which many people have been living for centuries.
A second theory contends that the Chaco structures were usedto store food supplies. One of the main crops of the Chaco people was grain maize, which could be stored for long periods of time without spoiling and could serve as a long-lasting supply of food. The supplies of maize had to be stored somewhere, and the size of the great houses would make them very suitable for the purpose.
A third theory proposes that houses were used as ceremonial centers. Close to one house, called Pueblo Alto, archaeologists identified an enormous mound formed by a pile of old material. Excavations of the mound revealed deposits containing a surprisingly large number of broken pots. This finding has been interpreted as evidence that people gathered at Pueblo Alto for special ceremonies. At the ceremonies, they ate festive meals and then discarded the pots in which the meals had been prepared or served. Such ceremonies have been documented for other Native American cultures.

Both the passage and the lecture are discussing the competing theories for the use of the great houses in New Mexico. The passage describes three possible theories for the function of the great houses. However, the lecture rejects the three theories mentioned in the passage.

First of all, the passage mentions one theory that the Chaco structures were purely residential by arguing that the Chaco houses are similar to the renown apartment buildings at Taos, New Mexico. In contrast, the lecture denies the theory by citing the evidence that the amount of the fire place is not comparable to the amount of the room. Since the number of fire place can only serve for ten families, yet the number of room can server for a hundred families.

Secondly, the passage describes another theory that the Chaco structures were used to store food. Nevertheless, the lecture questions the theory by stating that there were no residual of grain maize and big containers.

Finally, the lecture rejects the last theory in the passage that proposes the Chaco houses were used as ceremonial centers. Since the material found in the houses were the building material not used out for building the houses. Which it is possible that the pots found in the houses could be one of the trash left in the house as well.
